Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545680, here are decompositions:

23 + 33545657 = 33545680
29 + 33545651 = 33545680
71 + 33545609 = 33545680
83 + 33545597 = 33545680
89 + 33545591 = 33545680
101 + 33545579 = 33545680
197 + 33545483 = 33545680
251 + 33545429 = 33545680

Showing the first eight; more decompositions exist.
